Why there is a NZEC for the code given below.Frequently occuring in python 3.5

general
,
1

t=int(input())
c=[]
a=[]

for i in range(1,13):
c.append(2**(i-1))

for i in range(t):
count=0
int(count)
p=int(input())

while(p!=0):
i=0
while(c[i]<=p):
x=c[i]
i=i+1
p=p-x
count=count+1

a.append(count)

for i in range(t):
print("%d"%a[i])

the same happens for some of my Dlang ( D2 ) code, which makes me resort to C++
below is one of them

import std.stdio;
void main(string[] args) {
    uint testCases;
    readf( "%d\n", &testCases );
    while( testCases-- > 0 )
    {
        uint input, reversed = 0, temp;
        readf( "%d\n", &input );
        temp = input;
        while( temp > 0 )
        {
            reversed = reversed + ( temp % 10 );
            temp = temp / 10;
            reversed = reversed * 10;
        }
        reversed /= 10;
        if ( input == reversed ) writeln( "wins" );
        else writeln( "losses" );
    }

}
